This article reports that according to Olavo Correa da Silva, plant pathologist at Fundacao ABC, a large grower-funded research organization in Parana, Brazil, Asian soybean rust frequently appears as "hot spots" in soybean fields and can be controlled if found and treated quickly. But finding such hot spots is not often easy. So the best strategy for the disease for Brazilian growers is to time preventive sprays based on advisories from sentinel programs that track its movement geographically.
